In the event of faults and/or malfunctions,
GENERAL SAFETY INSTRUCTIONS
switch the appliance o and shut o the
gas valve. Do not attempt to perform any
repairs yourself but contact a qualified pro-
fessional instead.
Any repairs must be carried out by quali-
fied technicians using original spare parts
only. Failure to comply with the above may
jeopardise the device’s safety and void the
manufacturer’s liability.
In the event of any maintenance or other
work on structures in the immediate vicini-
ty of the ducts or flue gas discharge devic-
es and relevant accessories, turn the ap-
pliance o and on completion of the work,
have the eciency of the relative ducts or
devices checked by a qualified profession-
al.
5. Keep all packaging material (clips, plastic
bags, expanded polystyrene, etc.) out of
reach of children, as it may be potentially
dangerous.
6. The appliance can be used by children
older than 8 years and by people with re-
duced physical, sensory or mental abilities,
or who lack adequate experience and the
necessary knowledge, provided they are
supervised or have been instructed on the
safe use of the appliance and on the po-
tential risks connected with it.
Children must not play with the appliance.
Any cleaning and maintenance performed
by the user must not be eected by unsu-
pervised children.
7. It is mandatory to fit a regulatory safe-
ty valve onto the appliance’s water inlet
pipe. For countries that have implemented
standard EN 1487, the safety unit must have
a maximum pressure of 0.7 MPa and must
include at least a shut-o valve, a check
valve, a safety valve and a water pressure
shut-o device.
8. The pressure safety device (safety valve or
unit) must not be tampered with and must
be operated regularly to verify that it is not
clogged and to remove any limescale de-
posits.

GB
9. It is normal that the safety unit drip when
water is being heated. For this reason the
drain outlet must be connected and always
left open to the atmosphere, with a con-
tinuously downward-sloping drainage pipe
installed in a location which is not subject
to icy conditions.
10. The appliance must be drained and dis-
connected from the mains if it is to be left
inactive in a room subject to frost.
11. Hot water running from taps at tempera-
tures above 50°C may immediately cause
serious burns. Children, the disabled and
the elderly run a greater risk in this regard.
It is therefore advisable to use a thermo-
static mixing valve connected to the appli-
ance’s water outlet pipe (which is identified
by a red collar).
12. No flammable items should be left in con-
tact with or in the vicinity of the appliance.
13. Do not stand under the appliance or place
anything under it that may be damaged by
water leaks, for instance.
14. Do not use insecticides, solvents or ag-
gressive detergents to clean the appli-
ance; these may damage the plastic or
coated surfaces.

to the index corresponding to the de-
sired temperature: from 1 (around 42°C) to
7 (around 70°C).
A B C
To reduce gas consumption and run the ap-
pliance more eciently, it is best to leave
the knob at setting 5 (around 60°C).
This temperature also reduces the forma-
tion of limescale inside the water heater,
when the water supply is very hard (exces-
sive calcium content).
WARNING!
Water heated to more than 50°C
can cause serious burns. Always check
the temperature of the water before us-
ing it.

RECOMMENDATIONS
FOR PREVENTION OF LEGIONELLA
GROWTH
Legionella are small rod shaped bacteria
which are a natural constituent of all fresh
waters. Legionaries’ disease is a serious
pneumonia infection caused by inhaling
the bacteria Legionella pneumophilia or
other Legionella species.
This bacterium is frequently found in do-
mestic, hotel and other water systems and
in water used for air conditioning or air cool-
ing system. Hence the main intervention
against the condition is prevention, through
control of the organism in water systems.
The European standard CEN/TR 16355
gives recommendations for good practice
concerning the prevention of Legionel-
la growth in drinking water installations
but existing national regulations remain in
force.
This storage water heater is sold with a
thermostat set at a temperature higher than
60°C; it means it is enabled to carry out a
“thermal disinfection cycle” to restrict the
Legionella growth inside the tank.
To prevent it from stagnating for long peri-
ods, water must be used or run abundantly
at least once a week;
WARNING!
Water heated to more than 50°C can
cause serious burns. Always check the
temperature of the water before using it.

subject to vibrations.
When drilling the wall, take care not to
damage any existing electrical wiring or
pipes.
Make sure the installation site and any
systems to which the appliance must be
connected comply with applicable reg-
ulations.
POSITIONING
To allow easy access for maintenance,
make sure to install the unit with sucient
clearance around it.
Position the appliance according to es-
tablished technical rules, using a spirit
level.
The appliance mounts to the wall with
heavy duty hooks (rated to bear the
weight of the appliance when fully
charged with water) installed to the wall.
The clearances are given in the overall
dimensions table.
Place of installation
The choice of installation location must
observe applicable regulations.
The appliance must be installed perfect-
ly vertical. The appliance may not be in-
stalled in the vicinity of a source of heat.
Do not install the appliance in a place
where the temperature may fall below
0°C.
WATER CONNECTION
• Connect the heater to the water distri-
bution system using a 3/4” pipe. The
cold water inlet is on the right (blue
ring) while the hot water outlet is at the
left (red ring) as seen from in front of
the heater.
• The heater must be fi tted with a water
safety valve - non-return valve (sup-
plied with the heater) fi tted to the inlet
pipe (blue ring). You must not tamper
with the valve for any reason.
• Make sure by running the water for
some time, that there is no foreign ma-
terial in the water supply line, such as
swarf, sand, pipe dope etc.
Should any such material enter the
water safety valve - non return valve,
there can be faulty valve operation
and in some case faults to the valve
itself.
• Make sure that the water supply pres-
sure is lower than 8 bar (0.8 MPa). If
the pressure is higher, you must fi t a
high quality pressure reducer valve.
In this case the safety valve will nec-
essarily drip during heating. Said drip-
page must appear even if upstream of
the valve there is a non-return valve.
IMPORTANT!
If the appliance is installed in a hard wa-
ter area (> 200 mg/l), a softener should
be installed to limit the amount of limes-
cale building up in the heat exchanger.
The guarantee does not cover damage
caused by limescale.

GAS CONNECTION
WARNING!
Installation, first ignition and mainte-
nance work must be performed by qual-
ified personnel only, in accordance with
the instructions provided.
- Make sure that the main gas supply
matches the gas type on the unit’s
data plate
- Open all doors and windows
- Make sure there are no sparks or na-
ked flames in the room
- Water heaters are normally adjusted
for operation using methane gas G20
(PCI) 8100 kcal/m3 approximately. No
adjustment is needed if this gas is in
use.
Adjustment for other types of gas must
be done only by qualifi ed personnel.
- Use a 1/2” size pipe to connect the gas
supply to the valve.
- We suggest you fi t a stop valve in the
gas supply line, upstream of the gas
unit.
- Make the connection to the gas sup-
ply using rigid pipes (steel, copper
etc) and not thermoplastic nor rubber
pipes.
- After taking o the cover and making
the connection, check for leaks in the
gas system using soapy water.
Do not use a fl ame for this test.
The water heater has a magnesium an-
ode fitted in the tank. The life of the an-
ode
is proportional to the average tempera-
ture, the chemical composition and the
amount of water supplied.
We suggest you check the state of the
anode every 18-24 months, noting that
the surface must be relatively smooth.
If the diameter is less than 10-12mm, we
suggest you replace the anode with a
new original anode.
The anode is fi tted in the lower part of
the water heater, below the protection
cover.

7. Na rurze wlotowej urządzenia należy za-
montować zawór regulacyjny bezpieczeń-
stwa. W krajach, które wdrożyły normę EN
1487 jednostka bezpieczeństwa musi mieć
maksymalne ciśnienie 0,7 MPa i musi za-
wierać przynajmniej jeden zawór odcinają-
cy, zawór zwrotny, zawór bezpieczeństwa i
urządzenie odcinające ciśnienie wody.
8. Urządzenie (zawór lub jednostka bezpie-
czeństwa) nie może być naruszane i musi
być regularnie obsługiwane w celu spraw-
dzenia, czy nie jest zatkane i w celu usu-
nięcia wszelkich osadów.
9. Wycieki z jednostki bezpieczeństwa pod-
czas podgrzewania wody są normalną sy-
tuacją. W związku z tym, odpływ musi być
podłączony i zawsze pozostawiony otwar-
ty do otoczenia, z rurą spustową ustawio-
ną w sposób ciągły w dół, w miejscu, które
nie jest narażone na oblodzenie.

raturze powyżej 50°C może natychmiast
spowodować poważne oparzenia. Dzieci,
osoby niepełnosprawne i osoby starsze
ponoszą większe ryzyko. W związku z tym,
zaleca się stosowanie termostatycznego
zaworu mieszającego podłączonego do
rury wylotowej (która jest oznaczona czer-
wonym kołnierzem).
